Rotator Cuff Anatomy and Injuries

The video tutorial explains the anatomy and function of the shoulder's rotator cuff, which includes the Supraspinatus, Infraspinatus, Subscapularis, and Teres Minor muscles. These muscles stabilize the shoulder joint and facilitate various arm movements. The tutorial discusses common injuries, particularly to the supraspinatus, and outlines diagnostic methods such as the painful arc test and imaging techniques. Treatment options range from physical therapy to minimally invasive surgery.

Which muscles are part of the rotator cuff?

• Latissimus Dorsi, Trapezius, Rhomboids, Serratus Anterior
